Fig. 18 is a plan view thereof.

Figs. 19 and 2O are `plan views and side views, respectively, of an electric car with my attachments applied thereto.

Fig. 21 is a detail perspective view of a part of the mechanism shown in Figs. 19'V and 20.

Corresponding and like parts are referred to in the following description and indicated in all the views of 4the accompanying drawings by the same reference characters.

Our improved carrier system is particu larly designed for the purpose of carrying l dishes to and from a kitchen and dining room, though it is not limited to this -pur-.

pose, and to this end we have provided the endless elevated track which may be sup# ported in any suitable manner, either by posts or standards extending upward from the floor or by hangers depending from the ceiling, this track being formed with an elevated starting point, preferably in the kitchen, from which the track extends into lhe diningroom and continues back into the kitchen, the track being'inclined from the starting point to the end of the *.track.

Fig. 1 illustrates a plan view of the track system and shows four stations within the; dining room wherein thecars may be un-V loaded, though we do not llimit ourselves toV this number. In this ligure, A designates the kitchen and B the dining room while C designates a partition separating the kitchen from the diningroom. The high# v est point of the track is indica-ted by the K structed that upon the arrival of a car thereon which is setto actuate the elevator, the elevator will lower so as to carrytlie car :ownward to a point where it may be unloaded. f

Before describing the particular construc-l tion of the track, the elevators, the elevator actuating mechanism and the track brake actuating mechanism,l it will be best to describe the carwhich is adapted to run upon thetrack and to actuate any predetermined elevator. `One of these cars is illustrated in l Figs. 2,3, t and 5; The car platform which is designated 2is supported upon a rectangular truck frame 3 of any suitable character.

4^ This frame in turn is supported by springs i 4-from a rectangular frame 5 which is preferably formed of angle iron and which is disposed about on a level with the car axles.

'I Attached to each end of the frame -5 and projecting inward therefrom are the brackets or 'like supporting members 6 and pivotally mounted upon these brackets are' the front and rear axles 7 The axles are so pivoted that they -may be turned in a horizont-al plane as indicated in Fig. 5.

Mounted upon the axles7 are the wheels y 8. These wheels are of course freely ro-Y tatable upon the axles. The extremities of the axles carry roller bearings `9 which -bear against the under face of the frame 5. These rollers play Ybetween the under face of the truck frame 5 and the guide plate 10.

The axles 7 are pivoted upon `the brackets 6 for the purpose of permitting the axles to turn 4when rounding acurve so that thel car wheels may follow thecirve as illustrated in Fig. 5 and `als'o'so that thevaxles mayturn to permit the car wheels to properly track when the carpasses from a curve onto a straight track.l This is necessary where the cars are designed to. pass from a` starting point aroundl an endless track to return to the came starting point and where, there-y fore, there are necessarily curves around which the car has to pass. We have provided means for automatically actuating these axles 7 sov as to automatically guide the car around curves or ontoY a straight track. This means is particularly well illustrated in Figs. 3 and 4. l

Mounted upon each -of theside bars of the frame 5 rearward of the middle of the Canis an arm llwl'iich carries a'roller 12 at.

This brake 'sioe 29jhasupwardly extending terminal portions as' illustrated in' Fig. `2 and fearsinward ofthe terminalport'ions; f

The specific mannerby which the arIns'QSv lareconnected to the brake shoe lisv as follows.v

Eachafrin 28at its innerendis bifurcated as atBO and pivotally inountedbetween'the bifurcated end ofreach a'rni is a;block"31.

`This perniitsthe block ito'rotaterslightly.

Yplained later.

The lower end of each block is reduced slightly to lit inside of a coil spring 32. This spring presses up against a collar 33I and presses downwardly against an adjusting nut 34. This nut is threaded on aplunger 35 that passes upwardly through a perforation in block 3l. The lower end of each of these plungers 35 is pivoted to the upwardly projecting ears or lugs on the upper face of shoe 29. On the upper end of each of these plungers is an adjusting nut 36 whereby the height of shoe 29 may be adjusted.

Now it will be seen that when upward pressure is brought to bear against the under face of shoe 29, it will tend to rotate both 0f the shafts 26 applying the brake shoesr 27 upon the four wheels. In order to prevent any lateral movement tof the brake shoes we preferably provide a link 37 pivoted at its rear end to any suitable support, as for .instance the under facev of the supporting bracket 6, and at its forward end to the rear end of the brake shoe 29. The springs 32 are relatively strong and do not compressl until a pressure greater than necessary to apply the brakes is brought to bear against the. shoe 29. The adjusting nuts 36 limit the downward movement of the plungers 35 but allow the plungers to freely slide upthrough .the blocks 31 when the shoe 29 is raised higher than is necessary to apply the brakes.

It will of course be noted that the higher the shoe is raised, the stronger will be the stress on the springs 32 and the greater the strength with which the brakes are applied.

As previously stated, the car is provided with means whereby certain car shifting mechanism to be hereafter described is automatically operated. The mechanism for this lpurpose is illustrated clearly in Figs. 2 to 5 and consists of rollers 38, 38a and 381. These rollers are mounted upon a shaft 39mounted; in suitable bearings, the shaft extending transversely across the car above the brake plate 29. These rollers rotate freely upon the shaft 39 and are for the purpose of pressing downwardly against mechanism whereby track brakes, switches andelevators may be operated as will be more fully ex- The roller 38b is disposed adjacent the middle. of the shaft 39. and while it may rotate on the shaft it has no transverse motion. This roller is adapted to operate the several brakes on the terminal or kitchen end of track as will more fully appear later. Rollers 38 and- 38a are freely rotatable upon the shaft 39 and are also made to slide laterally on the shaft by means of levers 40 and 40a. By means of these levers the rollers 38 and 38a may be shifted in position. so. as to operateI on any desired elevator or like car shifting mechanism. The levers 40 and 40a are pivotally mounted upon brackets projecting from the frame 5 and at their forward ends they are provided with. the knobs 4 1'y whereby they may be operated. The outer ends 0f the levers are turned upward as at 42 so as to act as index pointers and these pointers move over a graduated plate 43 mounted upon the forward end of the car as illustrated in Fig. 2.

Now when it is desired` to operate a, certain elevator or like car shifting. device, one of the pointers, as for instance the pointer on lever 40, is. moved along the numbered plate 43 to the number of that elevator. This shifts the roller 38?L in a position totoperate that elevator, the roller 3S being moved ont of line of any elevator actuating device.

The ends of shaft 39 areV carried in the lower ends of plungers 44 and 45. These plungers pass upwardly each through a guide 46 carried upon the frame 5 and on the upper ends of these plungers are fitted collars 47 held in their places by coil springs 48.

As before stated, the. car platform 2 is mounted upon springs 4. To this end there are disposed at the four corners of the car kplatform the downwardly extending posts 49 whichV pass loosely through the truck frame 5. Fitted around the upperends of these posts are the springs 4 while disposed around the lower ends of the posts and disposed between the. collar 50 and the horizontal flange o f the angle frame 5 are the springs 51. These springs work in opposition to each other so that the car body is balanced between the upper and lower springs., These springs are compressed sufciently so that when the car is loaded to its full capacity the lower springs will still exert a slight pressure. By this arrangement it will be seen that the slightest load will be felt by the springs.

As before stated, the plungers 45 pass upwardly through guides 46. t The car platform 2 as illustrated in Fig. 3 bears upon these plungers. Thus when a heavier load is placed upon the car the rollers 38,A 38a and 38" will be forced down more strongly than when a lighter load is upon the car. This is for the reason that the brakes must be applied more strongly with heavy loads than with light loads in order to cause the car to stop at the same place as will be later described.

As illustrated in Fig. la, the track structure is supported by means of vertical standards or members designated generally 52. It will be understood that these vertical members may be extended upward either to the level of the track or vertically beyond the level of the track for certain purposes to be hereafter described but that all the standards without regard to their length are designated 52. These standards are connected by longitudinal members designated 53. The vertical members and the longitudinal members are .preferably formed ofangle iron lio isp

Tt will be seen that a depression of the platform 68 and a lifting up of the lever 86 will act to rotate the bell crank in the direction ofthe arrow Fig. 6.

The lower ends of the arms or levers 81 are connected to retractile spring 81a as will be later described.

Also mounted upon the shaft7 8 are the oppositely disposed, upwardly and rearwardly projecting arms 87 which at their upper ends are connected by links 82", each to one of the levers 56 as illustrated in Fig. 6. It will thus be seen that upon a downward movement of the platform 68 and an upward movement of the handle lever 86, the shaft 78 will be so rotated as to'cause'the arms 87 and the links/82b to move nearly into a straight line, thus raising the links 56 to the dotted line position shown in Fig. 6' and raising the track railsv a' to the level of the track rails m2. This upward movement of the elevator is cushioned by the cushion 64 as will bev later stated.

In order t0 hold the elevator in its lowered position andthe ltrack rails X in line with the track rails m1, we provide supporting brackets 88 which are mounted upon the standards 52 or upon` the cross'braces ofthe standards7 these brackets being adapted to support a cross bar 89 which is connected to the under `face of rails Pivotally mounted upon these brackets 88 is a bell crank lever 90. This bell crank lever has an upwardly projecting' arm and a forwardly' projecting arm; The upwardly projecting arm is formed with a latching head orl detent 91 while the forwardly projecting arm is connected' by a link 92 to a lever 98. VThis lever is disposed midway between the vertical supporting members 52 and projects rearward.

Pivotally mounted upon each platform 68 I is a treadle 94. The forward ends of these treadles are connected by means of a cross bar 95 which extends beneath the rear or free end of the lever 98 so that a depression of either one of the treadles 94 will cause the rear end of the lever 93 tol lift, thus drawing down upon the link 92, rotating the bell crank lever 90 and withdrawing the latch from the coacting membereon'the-track structure to permit the lifting of the elevator by the operator.

Mounted on the cross bar 89 and guided in a suitable guide formedl therein and disposed midway of the track rails m is a latching bolt 96. The rear end of' this bolt is V-supported in asuitable guide' on the' cross bar 54a to which the linksl 55 arepivotally connected. The lockingA bolt has upon it a collar 98 and disposed between the cross bar 54a andlthis collaris a= compressionspring'r 99 which acts to project the bolt.

Connected tol the bolt is a push r'od 1'00 which extends rearward and is connected? to the lower end' of aY pivoted. detent 101'.. This detent at its upper end is pivotally connect- 'ed to a brake` bar 102. One end ofthis brake bar is free for'vertical movement but the rear end thereofis pivotally supported upon a cross bar 1.03: Thisv bar 102 is adapted to engage 'with the brake shoe 29 on the car so as to set the car'brakes: Disposedv between the" brake bar 102and one of the rails t andladaptedi to bel engaged by the wheel 381 on `the' car is a plate 104 having an inclined entrance en'd 105.

Extending' transverselyl across the' track and rotatably mounted inv ears depending,

"plate- 104 will move equally. Projecting from the shaft 107 is the rearwardly prokjectingv tooth 111 adapted to engagel in a notch in the detent 101 or under a projecting portion of' the detent below the notch. A spring 112 is-attached to the downwardly extending arm 109l andto the links 55. This spring acts to resist the rearward movement ofthe link 110 and the rotation of the shafts 1'06 and 107i j For-the purpose ofl'ocking the elevator in its uppermost position, we-attach to the cross bar 113'- which supports: th'e rails :v2 the keeper 114 having a beveled lower face which is adapted to contact' with the extremity ofthe bolt 96 and force inward this bolt until it has passed the upper end of the keeperwhen the bolt will be projected out int-o engagement withthe-keeper as shown in dottedV lines in'y Fig; 6 and support the parts inr their' upraised position.

Thecrossbar 11B-is perforated just above the face of the keeper and passing through this perforation isa pushy pin 115l whose kextremityis connected-iI to an arm 1-16 mount- -edA upon a rock shaft 117. which rockshaft carries the :upwardly and.- forwardly curved arm' 118 which is located adjacent to one oftherails m2.

To this end we provide in advance-ot the actuating members 121 and. the brake member 1119 a brake plate 140 which is pivotally mounted at itsl rear end as previously described for the plate 119 and which isadapted to engage with the brake shoe of the` ear when it is raised. Mounted: adjacent to the plate 140` is the actuating plate 141 which has a beveled entrance end 142and which is pivotally connected to arms 143' and14-4 adj ustably mounted upon shafts.143"'and'144b respectively. The shaft 1431 has mounted upon it a bell crank lever 143a having a! rearwardly projecting arm 145 with a laterally disposed tooth engageable with aV detent 146 pivotally mounted. upon the` brake member rlhis detent 146 depends from` the brake member and? is notchedV uponfits rear edge as at 147. The depending end' ofthe bell crank 14321 is'connected by means ofthe rod` 148 with the depending arm 144 which is mounted upon the shaft 144`b so that the' arms 143 and144 will move-together, keeping the brake actuating bar 141 horizontal.

Pivotally mountedupon the brake-member 140= opposite the detent 146 is the depending latch 149 which may be engagedby the rearwardly` extending arnr of the bellcrank lever 1431l which at its middle is enlarged and formed with a slot 150. A rod 151-carriesl a piston152X which moveswithin the cylinder 1534 having therein. a; springv 154. This rod at one end is connected tothelower endV of the depending armi144a and; at its otherl end isconnected to the latch 149 by engaging in the slot 150 thereof. The lower end of the latch 149: has pivotedy thereto a rack bar155 which extends forward and whose'teeth engage with a pinion 156 mounted upon the shaft carrying a gear wheel 157. This gear wheel engages with a pinion 158 upon the shaft of which is mounted a rot-ating fan 159. device acting. to` retard thel rearward movement-of theV rack 155. A spring'159a isconnected at one endto the supports for the shaft 156 and at its other end is connected to the depending arm of the bell crank-143a so'as. to' tend to draw this depending arm forward and force the plate 141 upward.

The operation of this device is as follows. Vhen the first car arrives upon this section the roller 38b located4 beneath the cark comes in contact withy the brake actuating member 141 pressing it down. Thisaction rotates the arms 143 and 144 and the bell crank lever A143a lifting the rearward arm 145 of said lever andthe latch 149 that is engaged with it. This raises the brake bar 140 which,

ofcourse, applies the brakes to the car wheels as before. described. Now at the This fan forms a retardingY y another' car ahead, however, this other car has shifted: therod.r 1461- rearward latching the detent 146 with the bell crank 145-sothat the plate 140 will be prevented; from lower- Ving and, therefore, the car is held at this point until the car ahead moves 4on,.allowing push rod? v1-46f1to move forward, releasing the d'etentn 146, which,4 of course, allows the brake' plate 140ito lower, whereupon the car is free to'start.. l*

The rod 146s connects the detent 146 with the depending'arm of the lever 122 so that movement of thel lever is transmitted to the detent.

After the car has runupon the elevator section, it is unloaded of its empty dishes and filled dishesv are placed upon the car. It is then` in condition to be elevated to a level with the rails m2 so as'to permit the car to pass off and make its rounds upon the elevated track, the members 38 and 38a being so set as to actuateV any particular elevator to automatically lower the ear to a level. The raising' of the car is accomplished by the operator standing upon the platform 68,. depressing the locking lever 94 with his toot and. at the same time raising'up upon the leverV 86. This causes the elevator tolift to the position shown in dotted lines in Fig. 6 and brings the car to the level of the track m2, and permits it to pass off to the elevator E. This elevator is illustrated in; Figs. 7 and 8, Fig, 7 showing the elevator E in its normal position ready to receive a car, and Fig. 8 showing the elevator E depressed in position: to permit the unloading of the car and at the samev time permitting the passage of a. carupon the elevated tracks.

apositiony in line with the VILO vEach actuating member 210 is disposed in the path of a treadle 211, there being one treadle mounted upon each of the platforms 188. Each treadle is pivoted at its middle. `When the elevator is lowered `as shown in Fig. 8, the platforms are raised, thus br1nging the ends of the treadles 211 each beneath one of the members 210. When, therefore, it is desired to raise the elevator, the operator as before stated steps upon the corresponding platform 188, grasps the corresponding lever 180 and depresses thel inner end of the corresponding treadle 211. The outer end of the treadle engaging the arm 210 is thereby rocked and through the connection 209 rocks the shaft 207 and shifts the latch 204 outward, thus releasing the elevator and permitting its upward movement.

Mounted upon a cross bar 212 connecting the rails at the entrance side of the elevator as illustrated in Fig` 7 is a supporting catch 213 having a depending lip 214 formed with a beveled outer face. Mounted upon the cross bar 2122L of the exit rails w is vthe catch213a also formed with a depending lip having a beveled under face. These catches- 213-and 213it are for supporting the rails of the elevator in their lifted position and engage with said rails in the manner shown in Fig. 7. Y

lt is, of course, necessary tocheck a car after it has arrived upon the rails w3 and holdv it upon these rails as the elevator is lowered, and it is likewise necessary to re. lease the ear and permit its forward passage when the elevator hasbeen raised from Y a lowered to an elevated position. For this purpose we provide practically the same devices as have been heretofore described for automatically applying a brake upon the arrival of a car upon the rails m3, holding said brake applied and releasing the brake after the elevator has again moved u ward in ol sition to discharge the ear. It is alsovnecessary to provide mechanism whereby the elevater shall be locked in its raised position but automatically Vunlocked by a car having a nro Jerl set elevator actuatin devicethereon. The mechanism to this end is as follows. p l 1 i Mounted upon the under side ofthe rails w3 and extending transversely across these rails is a rock shaft 215 fupon which is mounted at one side of the middle line of the track the upwardly and forwardly rounded arm-216 which is disposed in the path of one of the elevator actuating rollers 38 or-38a when either one of these rollers is set for this particular elevator. Y

The shaft 215 has mounted upon itthe vertically disposed arms217 (see Figi 7 )p -The upwardly extendingfarm is connected lto a bolt 218 which passes-through alguide 219 carried upon across bar 220 and the eXtrem- 'f ityof lwhich-visadapted to engage withfthe position. The bolt 223 is forced outward by a'spring 226 which surroundsvthe bolt and which bears against a swiveled head 227 carried upon depending legs mounted upon the cross bar 161. i This spring 226 therefore will act to project both of the bolts 218 and 223 and consequently raise the arm 216 to the position shown in Fig. 7.

Assuming that the parts are in the position shown in Fig. 7 the wheel or actuating member 38 or 38er of the car if properly set will contact with the arm 216 and depress this arm thereby rocking the arms 217 and retracting the bolts 218 and 223, whereupon the weight 0f the car will cause the rails to descend. Upon an upward movement of the elevator, the inclined faces of the catches .213 and 21321 will force the bolts inward unforced inward by contact with the beveled face of the latch 206 and will catch beneath j this latch.

The rails m4 are provided at their ends with the transversely extending bars 228 attached t0 the under side of the rails from the ends of which project the outwardly eX- tending guiding lugs or tongues 229. Vhen these rails mi are depressed these guiding tongues will come in contact with the guides 230 which are attached to the upper faces of the cross bars 212 and 212A. As illustrated in Figs. 9 and 10 these guides are upwardly and outwardly flared and when the rails m4 descend'the tongues 229 will be guided by these guides 230v so vas to bring the rails fc4 into proper alinement with the rails m. The under faces of the cross bars 212 and 212a are also provided with the guides 231 which aredownwardly` and outwardly beveled or flared and thecross'bars 220 and 225 of the rails m3 are also provided with the forwardly projecting arms or tongues 232 which are adapted to engage with these guides 231 when the rails w3 are raised thus guiding the rails w3 into alinement with the rails Disposed inV line with the arm 216'is the brakev actuating plate 233.' This is mounted on the arms 234 and 234a which are attached Y respectively to the shafts 236 and 235 which 5236 are each provided with depending arms 238 connected to eachother by means of a vlink 239 so that the yarms 234 and 234a move together to raise or lower the plate 233.
